esp32Cam change resolution from mqtt

Hi…
Playing around with esp32cam…
As i’m new with esphome i’ve got a issue…

Is it possible to change the image resolution from via a MQTT message?
I’ve got this:

substitutions:
# Modify variables based on your settings
  hostname: 'esp-cam1'
  cam_resolution: '800x600'
  cam_fps: '5 fps'
...
...
esp32_camera:
  id: espcam
  external_clock:
    pin: GPIO0
    frequency: 20MHz
  i2c_pins:
    sda: GPIO26
    scl: GPIO27
  data_pins: [GPIO5, GPIO18, GPIO19, GPIO21, GPIO36, GPIO39, GPIO34, GPIO35]
  vsync_pin: GPIO25
  href_pin: GPIO23
  pixel_clock_pin: GPIO22
  power_down_pin: GPIO32

# Image settings
  name: esp-cam1
  resolution: $cam_resolution
  max_framerate: $cam_fps
  idle_framerate: 0 fps

where $cam_resolution is a variable…
I want to change the resolution of the camera by sending a MQTT message…
Is this possible?

I am not 100% sure, but I don’t think so. I am pretty sure it is compiled in.

If is changeable, there will be a setting in ha ui. Is there?

Thanks for the reply…
Welll, that would be a pity, I think it should be, as Tasmota WebServer and WebCam example from Aurdino makes it possible.

But I’ve been reading on the esp-home page, and the option to change resolution is not available yet…
